I recently worked with a surf casting bag manufacturer who was experiencing needle breaks during their sewing operation. (The term surf casting refers to surf fishing from the beach, typically in saltwater.)
The bags, made to hold tackle and gear, are manufactured out of a sail cloth material and are double stitched for added strength. During the operation, the sewing needles would begin to heat up, weaken and break, resulting in damaged product. The customer was considering using a Vortex Tube to blow cold air across the needle and while the Vortex Tube would work well in this application, I recommended using our Mini Cooler. The Mini Cooler is engineered to provide a focused stream of 20°F cold air (based on 70°F supply) while utilizing only 8 SCFM @ 100 PSIG. The Model # 3808 Mini Cooler System includes a swivel magnet base and single point hose kit, allowing for easy mounting and delivery of the cold air direct to the tool. Another advantage is that the Mini Cooler offers a shielded and muffled hot tube, which makes it better for operations where operators may come into contact with the tube. The perfect solution for a needle cooling application due to the fact it can easily be positioned and always puts out the 20°F air!
